Which Fraggle characters would work well on The Muppet Show?

Boober (his comic possibilities would be endless. I could see him as a recurring patient on Vet's Hospital, and predicting doom and gloom backstage)

Mokey (She and Janice would get along famously, resulting in more comic mishaps for Floyd, such as his having to care for Lanford AND keep an eye on Animal at the same time.)

Convincing John (This guy would truly be a menace backstage. I could see him as Fozzie's agent, or trying to con Kermit into going out to dinner with Miss Piggy...or being hired by Kermit to finally get Scooter to quit with the "My uncle owns the theatre" bit.)
